How to prune pomegranate trees

Pomegranate is one of the fruits that we often eat in our daily life, it has sweet and sour taste and beautiful color has attracted the attention of many people, of course, the most sought after is its powerful effect. Pomegranate is delicious, but there are many places that need to be paid attention to during planting, such as proper thinning and pruning.

How to prune pomegranate trees

1. Potted pomegranate should cut off excess branches and irregular branches. The pruning of seedlings is mainly pointed, usually at a height of more than 10 centimeters.

2. In spring, the withered branches, diseased branches and weak branches should be cut off, and the strong branches and crown should be retained, which is beneficial to promote the effect of multiple new branches, multi-flowering and multi-fruiting. Seedlings 10 cm high began to pick the heart many times, promoting branches to achieve crown fullness.

3. The dense part of the new lateral branches can be cut off from the base, at the same time, the full lateral buds can be formed in the axils of the leaves as soon as possible, and the dense needling-like short branches can be cut off.

4. When trimming, we should pay attention to the outside without leaving the inside, the straight without leaving the horizontal, and the cut to the outside.

5. The key point of pomegranate tree pruning should be the overgrown branches and the sprouting tillers in the rhizosphere, because the growing branches are not easy to differentiate flower buds and interfere with the shape of the tree, while the sprouting shoots in the rhizosphere germinate from the underground rhizosphere and grow faster than crown branches, but most of them only consume nutrients, so both kinds of branches should be pruned.

Matters needing attention for pomegranate tree pruning

1. Pomegranate trees should cut off withered branches, diseased branches, weak branches and long branches during overwintering in spring, and retain strong branches and crown shape, which is beneficial to promote the effect of multiple new branches, multi-flowering and multi-fruiting. Seedlings 10 cm high began to pick the heart many times, promoting branches to achieve crown fullness.

2. When pruning pomegranate trees, we should pay attention to the outside but not inside, straight and horizontal, and the cut should be kept outward.

3. The key point of pomegranate tree pruning should be the overgrown branches and the sprouting tillers in the rhizosphere, because the elongated branches germinate from the hidden buds in the cortex of the trunk or large lateral main branches, and grow erect or oblique above, but it is not easy to differentiate flower buds and interfere with the tree shape. The root sprouting tillers germinate from the underground rhizosphere and grow faster than the crown branches, but most of them only consume nutrients.

Cultivation techniques of pomegranate

1. Planting: pomegranate can be planted after falling leaves in autumn to before sprouting in the following spring. The soil should be sunny, leeward and slightly higher, and the soil should be loose, fertile and well drained. In the pot, the rotten leaf soil, the same soil and river sand mixed culture soil were selected, and an appropriate amount of mature organic fertilizer was added. Take soil mass when planting, trim the aboveground part properly, pour water thoroughly after planting, keep it in the shade, and move it to a ventilated and sunny place after germination.

2. Light: light and temperature are important conditions that affect the formation of flower buds. Full sunshine is required during the growing period, and the more abundant the light is, the more bright the flowers are. The leeward, sunny and dry environment is conducive to flower bud formation and flowering. The suitable growth temperature is 15-20 ℃, and the winter temperature should be lower than-18 ℃, otherwise it will suffer frost injury.

3. Water and fertilizer: pomegranate field cultivation must be reapplied with organic fertilizer once a year, and potted plants need to be fertilized for 1 to 2 years. In the growing season, we should also topdressing 3 to 5 times, and pay attention to loosen the soil and weed, often keep the basin soil moist, strictly prevent drought and waterlogging.

4. Harvest: the seedlings propagated by cuttings or ramets of pomegranate begin to bear fruit for 3-4 years, while the seedlings propagated by seeds take more than 10 years to blossom and bear fruit. Pomegranate blossoms 3 times a year, so it has 3 times of fruit, generally to head flower or two flowers and fruits develop well. It should be harvested in time according to variety characteristics, fruit maturity and climatic conditions.

Disease and pest control of pomegranate

1. Anthracnose was sprayed with 80-1000 times of methyl topiramate or 1000 times of Baogong, once every 7 days for 3 times in a row.

2. Branch blight was sprayed with 600x polysulfide suspension or copper oxychloride + chlorothalonil 1000 times, 2-3 times continuously and once every 10-11 days.

3. The algal spot disease was sprayed with 600 times of copper oxychloride suspension.

4. Cut off the seriously damaged branches and burn them, and spray the whole garden with 2000-fold solution of scale, or spray it with 2000-fold solution of scale and 1500-fold solution of imidacloprid.

5. Spraying imidacloprid 2000 times during the growth of new shoots can effectively control the damage of aphids.

Many things are hard-won, and such delicious pomegranates are no exception. Above, the pomegranate pruning methods and some matters needing attention during planting are introduced in detail. I hope it will be helpful to you. In addition, its pest control can not be ignored.
